Specialist note

With Patek Philippe Certificate of Origin dated 27 June 1991, glazed display back stamped 3970 and no. 2396050, fitted presentation box and outer packaging. Furthermore delivered with Patek Philippe Extract from the Archives confirming production of the present watch with silvery opaline-white dial and yellow gold indexes in 1991 and its subsequent sale on 27 June 1991.

Consigned by an important private collector and fresh to the market, this reference 3970 is preserved in excellent close to new overall condition.

Patek Philippe's celebrated reference 3970 was launched in 1986 and replaced reference 2499. The first generation was fitted with snap on case backs. Around 1989, the model was modified to a water-resistant version with screw back and was delivered with an additional glazed display back, such as the present watch. Reference 3970 remained in production until 2004 when it was replaced by reference 5970.

The model is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 305.
